Congenital antral webs are a rare but relevant cause of gastric outlet obstruction in infants and children. The condition may lead to feeding refusal, vomiting, and poor growth. Due to the relative rarity of the disease, cases of congenital antral web are frequently misdiagnosed or diagnosed with significant delay as physicians favorably pursue diagnoses of pyloric stenosis and gastric ulcer disease, which are more prevalent. We report a case of an eight-month-old female who presented with persistent non-bilious emesis, feeding difficulties, and failure to thrive and was discovered to have an antral web. The web was successfully treated with endoscopic balloon dilation, which resolved her symptoms. Two years later, the patient remains asymptomatic and is thriving with weight at the 75th percentile for her age.

The enzymatic hydrolysis of chitin has been studied for almost a century, and early work established that at least two enzymes are required, a chitinase that mainly yields the disaccharide N,N'-diacetylchitobiose, or $(GlcNAc)_2$, and a "chitobiase", or ${\beta}$-N-acetylglucosaminidase, which gives the final product G1cNAc. This pathway has not been completely identified but has remained the central concept for the chitin catabolism through the $20^{th}$ century1 including in marine bacteria. However, the chitin catabolic cascade is quite complex, as described in this review. This report describes three biologically functional genes involved in the chitin catabolic cascade of Vibrios in an attempt to better understand the metabolic pathway of chitin.
